Description
TECHNICAL FIELD
[0001] The disclosure relates to a multi-displayer scrolling
display technology, particularly to a multi-displayer scrolling
display method, device and processing terminal in a telepresence
system.
BACKGROUND
[0002] With the development of conference systems, people are no
longer satisfied with basic communication of conference contents,
and pursue comfort and on-the-scene feelings in communications. A
telepresence conference system developed for such a demand, e.g. a
telepresence system, which is an immersive virtual conference
technology, is able to provide a good on-the-scene feeling for a
conferee, including a life size, an eye contact and location
identification by voice, and so on, thus creating a face-to-face
feeling between two communicating parties. A life-size image can be
hardly provided by one camera plus a conference terminal display in
each conference place according to the prior art. Therefore, for a
current telepresence system, a plurality of cameras are generally
arranged in each conference place and support simultaneous display
of a plurality of video streams. FIG. 1 is a schematic diagram of
an arrangement of a telepresence conference place with three
displays, including three displays 101 arranged side by side,
telepresence desks 102 and telepresence chairs 103 provided
opposite to the displays 101, and so on. Life-size display and an
on-the-scene perspective can be achieved through the arrangement,
thus providing voices and images which are more realistic with more
on-the-scene feelings. Since a terminal is assorted with a display
in a certain conference place of a common conference system, all
original scrolling captions can be displayed on one display in a
scrolling manner. When a telepresence conference place is provided
with a plurality of displays, an original solution can only control
a scrolling caption or an image to be presented on a certain
screen, which is not user-friendly. Better user experience will be
achieved if a caption or an image can scroll on a plurality of
displays with a scrolling effect that the plurality of displays are
integrated as a whole.

DETAILED DESCRIPTION
[0028] The basic idea of the disclosure is that when a content
needing scrolling display is received, display positions and
display contents of the content needing scrolling display in
respective displays are determined according to an arrangement
manner, an output size and a scrolling display manner of the
displays of a telepresence system; the content needing scrolling
display is subjected to weighed stacking respectively with
originally to-be-displayed decoded outputted contents of the
respective displays, and respective contents subjected to the
weighed stacking are outputted as current frames of the respective
displays; whether display expires or scrolling display is cancelled
is determined; when it is time to terminate current processing,
display has not expired and scrolling display has not been
cancelled, display positions and display contents of the content
needing scrolling display in next frames of the respective displays
are determined according to the arrangement manner, the output size
and the scrolling display manner of the displays of the
telepresence system; the content needing scrolling display is
respectively subjected to weighed stacking with originally
to-be-displayed decoded outputted contents of the next frames of
the respective displays, and respective contents subjected to the
weighed stacking are outputted as the next frames of the respective
displays.
[0029] To make the purposes, technical solutions and advantages of
the disclosure clearer, the disclosure will be further expounded by
illustrating embodiments and with reference to the accompanying
drawings.
[0030] FIG. 2 is a flowchart of a multi-displayer scrolling display
method in a telepresence system according to an embodiment of the
disclosure. As shown in FIG. 2, the multi-displayer scrolling
display method in the telepresence system according to the present
example includes the following steps.
[0031] Step 201 includes that when a content needing scrolling
display is received, display positions and display contents of the
content needing scrolling display in respective displays are
determined according to an arrangement manner, an output size and a
scrolling display manner of the displays of a telepresence system;
and the content needing scrolling display is subjected to weighed
stacking respectively with originally to-be-displayed decoded
outputted contents of the respective displays, and respective
contents subjected to the weighed stacking are outputted as current
frames of the respective displays.
[0032] A caption to be displayed is configured through a remote
configuration interface (e.g. a web, or a console or a remote
control, and so on) of the telepresence system, e.g. the caption
may be "please have group discussions after the conference".
Parameters including a scrolling speed and a scrolling direction of
display are configured. A method of scrolling from left to right is
applied in the present example. In the disclosure, the so-called
caption is a text displayed as a lattice. Of course, a common text
may be also displayed directly if required, but the on-the-scene
effect will be modest.
[0033] A scrolling caption message is sent to each conference place
according to user configuration and a trigger method of the
telepresence system itself.
[0034] After receiving the scrolling caption message, a processing
terminal of a current conference place parses the scrolling caption
message in a memory into an exact lattice image that needs to be
superimposed (or stacked) with a content currently outputted and
displayed by a display. A specific method is that a lattice word
library preset by the processing terminal parses a scrolling
caption into a linear code stream that can be outputted and
displayed directly.
[0035] In the disclosure, a display content including an image etc.
may be also displayed in a scrolling manner according to completely
the same processing method of the scrolling caption, and an example
of display an image in a scrolling manner will not be illustrated
here.
[0036] Current arrangement positions of displays and sizes of
windows of the displays of the telepresence system are virtualized
in the memory of the processing terminal. In the disclosure, the
telepresence system is provided with a plurality of displays.
Generally, these displays are all arranged linearly in a single
layer as shown in FIG. 1. Of course, a multi-layer arrangement
method is also supported by a technical solution of the disclosure
and its implementing principle is almost the same as that of an
implementation method of single-layer linear arrangement, the only
difference lies in a slightly different method for computing a
display frame. Therefore, the disclosure provides illustration by
only taking the number of the displayers and the arrangement manner
thereof of the telepresence system as shown in FIG. 1 as an
example.
[0037] In the disclosure, parameters including the arrangement
manner, and a display size, and so on of the displayers may be
inputted into the memory of the processing terminal and served as
configuration parameters in order to improve the efficiency of
scrolling display, and the processing terminal only needs to invoke
the configuration parameters directly when it is needed to use
these parameters. Of course, it can be that only basic parameters,
e.g. sizes of the displayers, and arrangement orders among the
respective displayers and so on are inputted, so that the
processing terminal computes related display parameters according
to these configuration parameters.
[0038] FIG. 3 and FIG. 4 show a method for computing current
display positions and display contents of the scrolling captions in
the respective displayers in real time at a current moment, that
is, a coordinate system is virtualized, positions of the respective
displayers in the coordinate system are computed, and a display
position of each word in the caption needing scrolling display in a
current frame is determined according to the size of the caption to
be displayed and a display position of the caption in a displayer.
As shown in FIG. 3 and FIG. 4, display positions of current frames
of the scrolling caption on the respective displayers and display
contents on the respective displayers may be determined easily when
parameters including the arrangement orders of the respective
displayers, lengths and widths of the displayers themselves, the
size and the scrolling direction of the scrolling caption, and so
on are determined. The details of the determination process will
not be described repeatedly in the disclosure.
[0039] In the present example, a method for scrolling display is
scrolling display from left to right, and is not limited by the
disclosure. For example, the method for scrolling display may be
also scrolling display from right to left. Of course, if a display
system consists of displayers linearly arranged in two or more
layers, a scrolling caption may be hierarchically displayed
separately, or may be hierarchically displayed jointly. Since these
display methods may be implemented through specific arithmetical
operations and there are many display methods, it is impossible for
the disclosure to describe them one by one.
[0040] The Caption to be displayed on corresponding areas of three
displayers are outputted after being subjected to weighed stacking
with linear code streams parsed out by a decoder of the respective
displayers. That is, display positions and display contents of the
caption needing scrolling display on the respective displayers are
subjected to weighed stacking with originally to-be-displayed
decoded outputted contents of the respective displayers, and the
contents subjected to the weighed stacking are outputted as current
frames of the respective displayers.
[0041] Step 202 includes that whether display expires or scrolling
display is cancelled is determined; when it is time to terminate
current processing, display has not expired and scrolling display
has not been cancelled, display positions and display contents of
the content needing scrolling display in next frames of the
respective displayers are determined according to the arrangement
manner, the output size and the scrolling display manner of the
displayers of the telepresence system; the content needing
scrolling display is respectively subjected to weighed stacking
with originally to-be-displayed decoded outputted contents of the
next frames of the respective displayers, and the contents
subjected to the weighed stacking are outputted as the next frames
of the respective displayers.
[0042] In the disclosure, after a current frame is outputted, it is
necessary to determine whether a caption currently displayed in a
scrolling manner expires, or whether display has been cancelled by
a user. A current processing is terminated when display of the
caption displayed in a scrolling manner expires or the display has
been cancelled by the user. However, when scrolling display has not
expired or the scrolling display has not been cancelled, display
positions and display contents of the scrolling caption of next
frames on the respective displayers need to be determined according
to the speed of scrolling display, and are subjected to weighed
stacking with originally to-be-displayed decoded outputted contents
(contents displayed on backgrounds of the respective displayers may
have not been changed) of the next frames of the respective
displayers, and the contents subjected to the weighed stacking are
outputted as the next frames of the respective displayers.
[0043] In addition, after the determined next frames are output and
displayed as current frames, Step 202 is repeated until the
scrolling display is cancelled or expires.
[0044] FIG. 5 is a structural diagram of components of a
multi-displayer scrolling display device in a telepresence system

according to the arrangement manner, the output size and the
scrolling display manner of the displayers of the telepresence
system, display positions and display contents of the content
needing scrolling display in next frames of the respective
displayers.
[0050] The stacking unit 52 is configured to subject the content
